Race Date
Forbidden Run Fest • Nov 8
The smooth gravel surface of the trail makes it a perfect choice for runners, who usually run on pavement, but would like to run in an area immersed in nature on a surface that is more forgiving than pavement. And for the trail runners, we keep it interesting by adding a few trail sections as well.
Join us for a day of celebration and community in the heart of the Wissahickon.
